Iv'e got a 2003 KLT. Radio with 6 disc cd changer installed. No other communication gadgets factory installed. My Question is: When I scroll thru menus on radio it has Auxillary,CD Radio, etc as input sources. I now have a Zumo 550 on board and want to wire the sound from it to the Aux input on radio. Are these wires on the harness under the plastic on the bike? And are they labled clearly, or would you need a schematic or book to find them? I know that most with comm. have the unit where the front CD player is. Mine has player only ,not the voice comm. box. Thanks for any help with this!
